We compute the leading radiation-reaction acceleration and spin evolution for binary systems at linear order in the spins, which enter at fourth post-Newtonian (4PN) order. The calculation is carried out using the effective field theory framework for spinning compact objects in both the Newton-Wigner and covariant spin supplementary conditions. A non-trivial consistency check is performed on our results by showing that the energy loss induced by the resulting radiation-reaction force is equivalent to the total emitted power in the far zone, up to so-called “Schott terms.” We also find that, at this order, the radiation reaction has no net effect on the evolution of the spins. The spin-spin contributions to radiation reaction are reported in a companion paper.
